Application filed February 9,193i. Seriai a... 514,578.? I i attain an appreciable economy of floor space i in the use of looms of this class and at the same time have all the devices within easy reach of the weaver for his attention from In the present practice with the use of looms of this type if it is desired to doublev the length of the warp used it is the custom' to wind one-half of the double-length warp on each of two spools or equivalent devices (thus filling each to capacity) and then place these two, interlocked to rotate together, in alinement with each other and the corresponding ribbon-receiving device, or all on the same spindle again, if the ribbon required selvage it was the custom to wind the selvage warps on a separate spool or equivalent device and place this spool, interlocked with the body warp spool for rotation therewith, in alinement with such body warp spool, or with the receiving device and body and selvage warp spools all on the same spindle. In either case this meant serious encroachment on valuable floor space.

embodying the invention; and

V Fig. 2 shows one of the supplemental 'supply devices and its braking means in side elevation." 1 is the loom fr'ame; 2 the breast-beam carrying the glass-bars 3; 4 the suspended lay or batten structure; 5 the harness; and 6 the usual beamsupporting glass-bars 7 The warp 8 for each fabric extends from a supply spool or equivalent device 9 over guides, as rollers, 10 journaled in'the superstructure or castle 11 of the frame, a suspended loop 12 being formed'inthe warp etween some of said rollers and-sustaining a weightoryweights 13; from the rollers this warp extends under the glass-bars 7 forward through the harness and over the batten.

The ribbon 14 extends over the glass-barb, around the sand-rollers 15, over the pressure roller '16, back under the g'uide-barel'? and up tothe receiving spool 0mm 18. Each; two devices 9 and 18 are journaled on a single spindle 19 of the castle or superstructure, and they are separably intercoupled, as

in my said patent, so that they rotate as one, Wherefore the rotation of the core 9 under the pull of the warp as the weaving proceeds rotates core 18in the same direction, the rib-- bon 14 being ,wound on the core 18 as the warp unwinds from core 9. All this is the same as in my said patent.

At: the front of'the castlethere are spin dles, as 20, projecting forwardly. On each of these is revoluble a'spool' orother supply device 21 for the supplemental warp for each ribbon, and this has coupled to rotate therewith a flanged sheaveor pulley 22, such. coupling here comprisingstuds 23 and24 on the spool and sheave. The supplemental warp 25 for each ribbon 14; extends from the the castle, then back under one and forward over "another of the rollers 1O, then down between the latter roller and a third 'roller'10, in a bend or loop 27 sustaining a tension weight 28, then down under glass-bars 7,"

mass on the spool 21 up over a "roller 26 on where it.assumes the plane of the warp 8 and becomes thereupon woven into the ribbon 14. Attached at one end to a stud 29 on the castle is a flexible connection 30 which is given one or more turns around the sheave and has its other end attached to a weight 31, thus acting as a brake-member. Connecting the weights 28 and 31 is a wire or other link 32.

The operationof the improved loom, so far as the system comprising the ribbon and body warp 8 is concerned, is the same as in my saidf patent excepting. that the supplemental warp is derived from a supply independent of the devices 9 and 18, and has its V brake member holds the core 21 fast until two devices and supported on and at the front of said superstructure, said supplemental warp extending from said supplemental supply device over two of said guides and to the fabric, means to tension the supplemental warp engaging the same between the guidesengaged thereby and maintaining a bend therein, and means, controlled by said bend, for controlling the rotation of the sup plemental supply device, said frame having means, coactive with the first two guides, to guide the fabric and both warps.

'Intestimony whereof I afiix my signature.

the loop 27 has in the weaving been taken up" I V sufficiently to act throughclinkv 32 to relax 20 the braking action, whereupon the brake lets go, the weight '28 draws ofi warp from-said core bycausingiot-ation thereof With conse-- quent re-extension of the loop and re-settilig ofthe braking-action on said core.

It willbe noted that my arrangement avails itself .of .the same guides 10 for the selvage w-arpsithat aroused-for the body warp, so-that additional guides are avoided andthe selvage warps and body ,warpextend,

am as heretofore,- subst-antially together down'to the glass-bars 7..

Having, thus fully-described my invention what :I claim. is

1. In a*loom,.the combination of. thejframe 35. having. a superstructure, a rotary fabric receiving device and a warp supplydevicecon nectedto rotate together whereby'to wind the vfabric on said receiving. device as the warp is unwound from said supplydevice, 1 said devices being v supported on and at the. back'of said superstructure, means to tensionthe bandflformedby the warp andrzfabric, a-

supplemental. warp supply device on which. a

supplementallwarp is -wound .rotative inde- ::pendentl-yof the-first two devices and supported .on .and at the front of the super structure, and meanswto tension the. supple-. mental warp independently of said band,

:and both warps.

2-. ..In-a.loom,-the combinationof the frame having. a superstructure including: spaced"v guides, arotary fabric receiving device and a warp supply device connected to rotate toe gethenwherebyto wind-the fabric on said receiving .device as the. warp is unwound from said supply device, said devices being supported at theba-ck of said superstructure and the..-warp extendingbvertwo' of said guides, "means to tensionathe band" formed the warp and fabric and engaging .the

warp between: said guides and maintaining az'loop therein, a :supplementalwarpsupply device :on: which a supplemental warp' iswound l rotative: independently, of the first said frame having means .to guidethe fabric
